DRAFT-RIGGING.

SPECIFICATION forming part of Letters Patent No. 614,262, dated.November 15, 1898.

Application filed January 2,8, 1898. Serial No. 668,279` (No model.)

To a/ZZ whom t may concern.-

Beit known that we, JOHN EDWARDS, of Homestead, JOHN R. DAvIEs, ofDuquesne, and JOHN J AREETT,of Pittsburg, in the county of Allegheny andState of Pennsylvania, have invented a new and useful Improvement inDraft-Riggings, of which the following is a full,clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in Which- Figure 1 is a partial longitudinalsection of the end of a car, showing our improved riggingin position.Fig. 2 is a bottom plan view of the same, partly broken away. Fig. 3 isa front elevation. Fig. 4 is a transverse section on the line IV IV ofFig. 1; and Fig. 5 is a detail perspective view, showing one of thedraft-irons.

Our invention relates to the draft-riggings of railway-cars, and isdesigned to provide a device of this character which shall be simple andcheap of construction, in which the strain, whether-of tension orcompression, shall be equalized and distributed on opposite sides of thedraw-bar, and in which the parts can be easily-removed and replaced.

In the drawings, 2 2 represent the drafttimbers of a car, and 3 3 twoZ-bars, the upper flanges 4 of which iit in suitable recesses in theupper faces of the draft-timbers. At their front ends these Z-barsarecut down, so as to form a lateral iiange or lug 5, which is secured tothe draft-timber by a lbolt 6. Near their front ends the lower dependingportions of the Z-bars are slotted horizontally at 7 to receive atransverse connectingbar 8, which passes through these slots and throughslots in the U-shaped strap 9, which encircles the rear end of thedraw-bar 10. Surrounding the end portions of ,the bar 8, outside thedraft-timbers, are the yokes 11 11, secured to the rearwardly-extendingrods or stems 12, which pass through the crosstimber 13. Between thiscross-timber and the straps or yokes 11 and surrounding the rods 12 aresprings 14, and in the rear of the timber are the similar springs "15,which abut at one end against the timber and at the other against keys16 in the rods. The bar 8 is provided at one end with a head 17 and whenit is slipped into place it is secured by a key 18, driven through aslot in its other end.v The cross piece or timber 13 passes throughslots 19 in the draft-irons and when in place is secured by the bolts20. When these draftirons are put in position between the drafttimbers,the' spacing-block 21 is driven into place between them and secured bythe through-bolts 22.

The rear ends of the Z-bars are slotted, as shown at 23, and a strap 24extends across ltheir rear ends, within the slots, this strap being heldin place by a block 25, fitting in a recess in cross-sill 26 and intothe recesses of the Z-bars, this block being held in place by anysuitable means.

To assist in taking up compressive strain, we preferably provide thedraw-bar 10 with inclined edge faces 27, against which blocks 28, havingcorrespondingly -inclined faces, are yieldingly pressed by a bolt 29,entending through the slot in the draw-bar. The springs are held withinsuitable sockets 30, and when the bufling action occurs the blocks,riding up the inclines, will cushion the blow and take up the strain.

In the operation of the device when a pulling strain is exerted upon thedraw-bar the rods 12, being pulled forwardly, will compress the springs15 and drive the blocks 28 up the inclined faces of the draw-bar, thestrain thus being equalized and distributed upon both sides. Similarly,in bufting, the rods being moved rearwardly will compress the springs14, the strain being distributed as before.

The advantages of our invention will be apparent to those skilled in theart, since the rigging is of few parts, which parts are simple and canbe cheaply made, while the strains are evenly and uniformly distributed,thus preventing liability to injury of the rigging. The draft-irons maybe easily and quickly removed and replaced without tearing up the floorof the car, and any of the other parts of the rigging may be easilyreplaced by removing the block 25 and disconnectingthe parts.

Modifications in the form construction, and relative arrangement of theparts of the device lnay be made by those skilled in the art withoutdeparture from our invention, since IOO ing on the top `of` thedraft-timbers, and aspacing-block securedbetwe'en the draft# irons andthe timbers, `substantially as des scribed.
